John Maynard Keynes Quotes

The ignorance of even the best-informed investor about the more remote future is much greater than his knowledge, and he cannot but be influenced to a degree which would seem wildly disproportionate to anyone who really knew the future, and be forced to seek a clue mainly here to trends further ahead. But if this is true of the best-informed, the vast majority of those who are concerned with the buying and selling of securities know almost nothing whatever about what they are doing. They do not possess even the rudiments of what is required for a valid judgement, and are the prey of hopes and fears easily aroused by transient events and as easily dispelled.

Capitalism... is absolutely irreligious, without internal union, without much public spirit, often... a mere congeries of possessors and pursuers. Such a system has to be immensely, not merely moderately, successful to survive.

On the economic side I cannot perceive that Russian Communism has made any contribution to our economic problems of intellectual interest or scientific value. I do not think that it contains, or is likely to contain, any piece of useful economic technique which we could not apply, if we chose, with equal or greater success in a society which retained all the marks... of British bourgeois ideals.

How can I accept a doctrine which sets up as its bible, above and beyond criticism, an obsolete economic textbook which I know to be not only scientifically erroneous but without interest or application for the modern world?

There is... no so-called important political question so really unimportant, so irrelevant to the re-organization of the economic life of Great Britain, as the Nationalisation of the Railways.

Marxian Socialism must always remain a portent to the historians of Opinion—how a doctrine so illogical and so dull can have exercised so powerful and enduring an influence over the minds of men, and, through them, the events of history.

There is no party in the world... pursuing right aims by right methods. Material Poverty provides the incentive to change... where there is very little margin for experiments. Material Prosperity removes the incentive just when it might be safe to take a chance.

Capitalism, wisely managed, can probably be made more efficient for attaining economic ends than any alternative system yet in sight, but... in itself it is in many ways extremely objectionable. Our problem is to work out a social organisation which shall be as efficient as possible without offending our notions of a satisfactory way of life.

The time has... come when each country needs a considered national policy about what size of Population... is most expedient.

It is because particular individuals, fortunate in situation or in abilities, are able to take advantage of uncertainty and ignorance, and also because for the same reason big business is often a lottery, that great inequalities of wealth come about; and these same factors are also the cause of the Unemployment of Labour, or the disappointment of reasonable business expectations, and of the impairment of efficiency and production.

Many of the greatest economic evils of our time are the fruits of risk, uncertainty, and ignorance.

The important thing for Government is not to do things which individuals are doing already... but to do those things which at present are not done at all.

We must aim at separating those services which are technically social from those which are technically individual. The most important Agenda of the State relate not to those activities which private individuals are already fulfilling, but to those functions which fall outside the sphere of the individual, to those decisions which are made by no one if the State does not make them.

It is not a correct deduction from the Principles of Economics that enlightened self-interest always operates in the public interest. Nor is it true that self-interest generally is enlightened; more often individuals acting separately to promote their own ends are too ignorant or too weak to attain even these.

It is not true that individuals possess a prescriptive "natural liberty" in their economic activities. There is no "compact" conferring perpetual rights on those who Have or on those who Acquire.
